An abrasive flow machine normally includes two medium chambers equipped with hydraulic rams, a fixture for holding the workpiece, and a clamping system nltel holds all the components tightly together. Deburring and Edge Handbook Illustrated ed. Retrieved from ” https: Certificate will have your name, photograph and the score in the final exam with the breakup.

AFM avrasive be performed once, as a one-way flow process, or repeatedly as a two-way flow process. In the two-way flow process, a reservoir of medium exists at either end of the workpiece, and the medium flows back and forth through the workpiece from reservoir to reservoir. Magnetic Abrasive Finishing Week 7: Views Read Edit View history.


Abrasive flow machining was first patented by the Extrude Hone Corporation in The nature of AFM makes it ideal for interior surfaces, slots, holes, cavities, and other areas that may be difficult to reach with other polishing or grinding processes.

Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them.

They may be manually operated, or automated using CNC. In abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. Abrasive flow machining AFMalso known as abrasive flow deburring [1] or extrude honing[2] is an interior surface finishing process characterized by flowing an abrasive -laden fluid through a workpiece.
